Since explaining link to Bosch, Braun mum

MILWAUKEE -- A spokesperson for Ryan Braun's agency on Wednesday declined a request from MLB.com for further explanation of the All-Star outfielder's link to Anthony Bosch, the former head of an anti-aging clinic under investigation by Major League Baseball.

Braun was connected to Biogenesis on Tuesday night, when Yahoo! Sports published excerpts of Bosch's notes that included three mentions of Braun. In one of them, Braun's name appears above "RB 20-30K," a notation similar to instances in which Bosch listed the amount of money owed by some alleged clients.

But Braun was never implicated in the documents as having received substances, and he quickly offered an explanation of his presence in the ledger, saying his attorneys had used Bosch as a consultant while working on Braun's appeal of a suspension during the winter of 2011-12 -- a case Braun and his team ultimately won. The lawyer who headed Braun's defense, David Cornwell, released his own statement confirming Braun's characterization, saying he had met with Bosch but characterized Bosch's contribution to the case as "negligible."

"There was a dispute over compensation for Bosch's work, which is why my lawyer and I are listed under 'moneys owed' and not on any other list," Braun said on Tuesday night. "I have nothing to hide and have never had any other relationship with Bosch. I will fully cooperate with any inquiry into this matter."

On Wednesday, Braun's representatives fielded requests from a number of news outlets, including MLB.com, for documentation to support Braun's explanation that Bosch was used only as a consultant.

Through the Creative Artists Agency, which has represented Braun throughout his professional career, Braun and his lawyers said they had no additional comment.

Several factors could explain that stance. Attorney Wendy Thurm wrote for the website FanGraphs.com on Wednesday that "the work of behind-the-scenes experts, or consultants, is considered confidential and within the ambit of the attorney-client privilege and attorney work-product privilege."

There is also the ongoing matter of MLB's investigation into players' connections to Biogenesis. The league could levy punishment where appropriate, even in the absence of a positive drug test.
